Removable vane cover fastened to a conventional vertical blind system

ABSTRACT

A vertical blind system includes a conventional vertical blind mechanism, a plurality of Elongated vertical blind vanes preferably of opaque or semi opaque rigid material such as Plastic, aluminum or stiff fabric, pivotally mounted to the vertical blind mechanism; a continuous blind vane cover sheet selected from the group consisting of translucent, or transparent material such as sheer or lace fabric. The cover sheet forms a U-shaped folds that extends between the adjacent blind vanes and removably are secured to the blind vanes at a predetermined spaced intervals by material fasteners. The materials fasteners are constructed and arranged to allow the cover sheet to be detached and reattached to the blind vanes for washing and cleaning, or changing by new. The cover sheet could be secured to a plurality of rigid slats oriented horizontally, thus requiring the use of a different operating system such as a conventional horizontal blind slat mechanism.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to window coverings and more particularly, but not exclusively, the present invention relates to a cover in nature of a transparent, yet translucent removably fastened to a plurality of vertical blind vanes and or horizontal blind slats.

2. Description of the Prior Art

A common covering system for windows is a vertical blind having vertical vanes rotatable about vertical axes to an open or closes position.

The covering system may further include a decorative cover fabric extends across vertical blind vanes so as to control the amount of light entering the room and to provide an aesthetically pleasing appearance.

In U.S. Pat. No. 3,844,330 issued in 1974 to louver Drape. Inc. there is disclosed a window covering system using conventional vertical blind hardware employed with vertically disposed louvers according to this 330 patent, the window covering made of one kind of continuous material, in order to achieve the decorative effects, this disposed louver system must positioned behind a separate drapery system, or associated with drapers, the drapery material may be pinch pleated and attached at the front of each louver.

U.S. Pat. No. 3,851,699 issued in 1974 to Shapiro, U.S. Pat. No. 3,946,789 issued in 1976 to Ronkholz, U.S. Pat. No. 4,846,243 issued 1989 to Schneider, U.S. Pat. No. 5,419,385 issued 1995 to Vogel, U.S. Pat. No. 5,715,883 issued 1998 to Keith, U.S. Pat. No. 6,164,363 issued 2000 to Colson and U.S. Pat. No. 6,186,213 issued 2001 to Senesac. discloses a vertical louver type window drape where a continuous sheet of fabric material is interwoven with a plurality of relatively rigid vanes such that the vanes which are light impeding alternate with light transmitting sections of the fabric. Two obvious drawback of a system of this type is that the vanes overlap the fabric requiring excessive fabric in order to fabricate the entire window covering, and a user can not separate the continuous sheet of fabric from the rigid vanes.

Window coverings of the afore—no ted type as mentioned previously are desirable from several viewpoints. It has also been discovered that variation in this general type of window covering may be desirable from many stand points, both utilitarian and aesthetic. It is to provide alternatives and improvements to the afore described prior art systems that the present vertical blind and horizontal blind system have been developed.

Fabric window coverings are often preferred by consumers for a number of their features. Features most often considered desirable are the softer appearance relative to traditional Venetian blinds, the uniform appearance which they provide a window and insulating properties associated with cellular fabric shades.

Cellular fabric shades offering these features are known in the art. For example, U.S. Pat. No. 4,450,027 to Colson discloses cellular window coverings which may be made of fabric or fill materials. In the process disclosed in the Colson patent, a flexible strip of material is folded into a continuous longitudinal tube and the longitudinal folds thus created are currently set by passing the tubing material around a heat setting wheel. Adhesive is applied along one side of the flattened tubular material which is subsequently stacked by winding onto a rack having flat surfaces. The winding in this manner presses the adhesive to the next layer wound onto the rack to form a bonded unitary stack of closed tubular cells. When the ends are cut from the rack, the stack may be expanded and the permanently set creases provide a neat and uniform outward appearance.

U.S. Pat. No. 4,732,630 to Schnebley discloses a modification to the Colson process described above. In the Schnebley patent, a hot melt adhesive is applied to one side of the tubular material. After the flat tubular strips have been stacked and cut, they are placed in an oven under pressure and the hot melted adhesive is activated to bond the layers together.

Both of the above patents disclose window coverings which exhibit the desirable features discussed to this point. However, window coverings of that type lack one feature which is often desired by consumers. That feature is the ability to control the amount of light admitted through the window covering, similar to a traditional Venetian blind. There have been some attempts to provide a fabric window covering with the ability to control the amount of light entering the room.

In some attempts, the decorative cover may be removable from the blind vanes to enable a user to clean the fabric cover or to replace with new.

OBJECTS OF THE INVENTION

It is therefore a general object of this invention is to provide alternative and improvements to this type of window covering.

A primary object of the present invention is to provide two different types of rigid and flexible fabric material in combination, first type is a plurality of conventional vertical blind vanes and a second type is a decorative fabric cover extends across the vertical blind vanes.

Yet another object of the present invention is to provide a decorative cover fabric extends on an array of conventional horizontal blind slats.

Still yet another object of the present invention is the provision of a window curtain which combines the desirable characteristics of both a conventional vanes type vertical blind and a decorative window drape, affording the adjustable light transmission features of a vertical blind while retaining the esthetic characteristics of a window drape.

Another object of the invention is to provide such a fabric cover, which will be attached to existing, already installed, vertical blind vanes, without any structural modifications being called upon.

Still yet another object of the present invention is that the above-noted combined blind vanes and fabric cover type drape be capable of continuously adjusting the light—diffusing ratio through the drape.

A further object of the present invention is that the above-noted combined blind vanes and fabric cover type drape require very little skill for its installation, and little time to complete the installation.

Additional object of the present invention will appear as the description proceeds. The description reference is made to accompanying drawings, which forms apart here of, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. IN the accompanying drawing, like reference characters, designate the same of similar parts throughout the several views.

The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present invention is best defined by the appended claims.

SUMMARY OF THE INVENTION

The present invention adds additional features to both, the conventional vertical blind vanes system and the horizontal blind slats system to enhance interior design aspects. In particular, a cover sheet is attached to the front edge of the blind vanes to provide an aesthetically pleasing and softening appearance of the blind when the blind is closed, opened, or partially open position. In accordance with the teaching of the present invention there is disclosed, certain of its features of one embodiment of the invention can be described briefly.

A vertical blind system includes a conventional vertical blind mechanism and a plurality of vertical blind vanes being pivotally mounted to the vertical blind mechanism which can pivot the blind vanes about vertical axis from open position to a close position, and can traverse the blind vanes to the side (retracted position).

A continuous decorative sheet is removably attached to the blind vanes at a predetermined spaced interval, the decorative cover sheet attached to the blind vanes by using of a plurality of material fasteners. The material fasteners are constructed and arranged to allow the fabric cover to be detached and reattached to the blind vanes for washing and cleaning.

No limitations are contemplated as to a particular embodiment of the blind vane mechanism employed in a vertical blind system of the present invention, and any conventional mechanism can be used, provided vanes are adapted for use with connectors near their tops for mounting the blind vane cover of the invention as claimed here in. The present invention further contemplates that the vertical blind vanes and the blind vane covers can have any configuration, can have any suitable dimensions, can be made from any suitable material, and may or may not be decorative.
